To all 'iv/tom t 'may concern Be it known thut l. l.\'rnu'k .\l,\noxr.v.n citizen of the United States, reddingq nt lortlnnd. in the eountv ot(hunherlutul und Stute olI Muine, hure invented rertuiu new i und n efullm|novements i`n Devires for Maintaining :i llnlt'orm Deltverv of interlowing is :L lpeeilirnlimr My invention relzttes tol improvementv indevice4 for muiutniniugr :t uni'l'ornl deliver)v of water under vnr vin;lr prewure. und l have illustrated the unie n upplied to what ipopularly culled l\:|uit:|r,v drinkingr l'ouutnins, hut the use ol the:'ippnrutuh in not limited to this pui-pme und npplieunl dow not intendto limit itxV use ill :tnv wuv other than :is is hereinn'l'ter yset outin the rlnium.

In an apparatus for thedelivetv of waiter from a supply under prenten-e,which pres;- sure is subject to variations due to any cause, andespecially in drinking fountains of the class designed for the drinkerto hike.

the water directlyr into the mouth from n column of water, it is foundto he' :u'l'vnntw geous to provide means 'for maintaining the column ofwriter nt. nsuhstnntinlly uniform pressure. Appliezints device isespecially designed for this purpose. To this end, it consists of nhoming A. n couplingr B ndnpted to connect. it. with :t witter supply. nverticnl spindle (l. mounted in Suid coulpliug undv provided with one ormore vertieuports l). The lower end of the spindle tu eup-shnped, as:seen nt 1".. :intl lending thereonto'lnre ports F in the vertit'nl wnllsther'eoli und in the 4top nre, ports (i opening` into the ports I) inthe spindle, the lower portion ofthe ports l) is of greater enpneitythun the upper )o1-tion.

To prevent witter from sputtering if the end ofn the nozzle. is closed Iprovide the nozzle S inside the housingwith ports 1 extending diagonnllti wnrdly. This does not interfere with tie r elivery of the waterthrough the end. of the nozzle nnd if the nozzle is closed., instead ofthe water squirtingr` out, it flows hack through the opening l into theterminal R und thence throughthe orts 2 to the outside.

'1 le operation of my `improved device is :is follows: The waterentering the chamber tl'irough ports l1` pannes thence into the port` inThe spindle und, when the presure is noi-nml, the limiting ring II ismoved nlp wardly 'against the stop K so ns to close t e PWH 0 in theAtop und then all the witter delivered will he through the. ports l) in[f the normal. pressure is dis- A downwardly, thus o enin the ports U sothat water will be de ivere to the nozzle, not only through the ports Din the spindle but through the orts O in the stop.

Havin thus drscribed my invention and its use, claim:

1. In a device of the character described, a housing, a spindle mountedtherein and provided with vertical ports a stop secured to the top ofthe spindle and provided with vertical orts, a floating ring positlonedbe lour sai stop, and a spring inter osed between said sto and ring andten ing n ormally to hold t em apart, sa1d iloat1 ng ring being adaptedto be held agalnst the stop and to close the ports therein when thepressure is normal and to be forced away to open said ports when thepressure is diminished.

2. In a. device of the character described, a housing, a spindle mountedtherein and provided with vertical ports tapering up' wardly, a stopsecured to the to of the s indie and provided with vertice ports, a

eating ring positioned below said stop,

land-a spring interposed between said stop und ring and tending normallyto hold them apart, said floating ring being adapted to be held 'againstthe stop and to close the ports therein-when the pressure' is normal andto be forced away to open said ports when the pressure is diminished.

3. In a device of the character described, a housing, a spindle mountedtherein and provided with vertical ports, a stop Secured to the top. ofthe spindle and provided with vertical dports, a' floating ringpositioned below sai stop, a spring intel"- posed between said sto 'andring and tendmg normal] to hold t em apart, said iioating ring beingadapted to be held against the stop and to close the ports therein whenthe pressure is normal and to be forced away .to open said ports whenthe pressure is diminished, and means for regulating the capacity of theports in the spindle and in the stop.
